Solutions for life

As the world’s second-largest mold maker, SIPA is able to deliver global tooling programs for new molds or mold conversions from single to 144 cavities.To ensure top quality, every SIPA mold is tested before shipping on dedicated XFORM machines. Over the years we have developed extensive knowledge of many different applications, even the most specialised ones, from narrow necks to wide mouths and thick walls.

XMOULD is an innovation from Sipa which allows reduction of friction between molten PET and molding surface of the injection stacks during injection phase, allowing production of thin-wall performs with length on wall thickness ratio above 50 (L/t in the range of 50 to 55 possible), so better/optimized thickness distribution on final packaging (avoid the accumulation of material on zone as under-neck and bottom areas).

XMOULD technology gives designers the power to create lightweighted preforms which do not compromise performance of the final container. Besides the possibility to reduce preform thicknesses, this solution also improves cycle times due to friction reduction at filling phase.

Available on new or legacy tooling, only special injection stacks are required to enjoy the XMOULD technology, no changes required neither on the machine nor the hot runner.

Smart lock design applied regardless of the position of the parting line: better precision and higher durability with double tapers always implemented

Flange design to allow a significantly better cooling in the very critical split-line area

Self-centering gate insert, allows for a reduction of the parting line in the base area of the preform

Applications

Our range of solutions is wide and versatile. We can supply moulds with up to 144 cavities for standard applications like mineral water or soft drinks, however we have a wide range of solutions also for special applications like wide mouth preforms or long preforms for 5 gallon containers.
